From 5906f54e474c6e8aabb0f6b955d446b509cde06e Mon Sep 17 00:00:00 2001 From: Jay Soffian Date: Tue, 31 Mar 2009 12:22:11 -0400 Subject: send-email: don't attempt to prompt if tty is closed Attempting to prompt when the tty is closed (typically when running from cron) is pointless and emits a warning. This patch causes ask() to return early, squelching the warning.
